| Summary: | The aquaculture industry has made a great contribution towards economic development of Malaysia.
However, the large volume of water consumption and the wastewater discharged into the water source caused
a significant environmental problem that must be controlled properly. For instance, aquaculture waste may
decrease dissolved oxygen level and load high nutrient and inorganic contaminants which subsequently would
cause water deterioration. Thus, to ensure the effectiveness of aquaculture practices, the suitable wastewater
management approach should be acquainted. Phytoremediation, which are the application of plant-based
technologies, are beginning to be accepted to examine the problems and provide sustainable solutions for this
issue. Therefore, this research aims to explore ecological approach by developing phytoremediation model
system in order to remediate inorganic pollutants produced by aquaculture pond. In this paper, the efficiency
of potential aquatic plants which are Glossostigma elatinoides and Hemianthus callitrichoides to sequester
cadmium and copper were investigated. To achieve this, phytoremediation model system was developed using
two selected species for three different concentrations of cadmium (Cd) and copper (Cu). This model system
was run over three different periods of time, which are week 1, week 2, and week 3. The findings of this
research suggested that the capability to sequester different concentration of heavy metals for certain periods
of time were varied between different species. The results indicated that Glossostigma elatinoides was a good phytoremediator for Cd whereas Hemianthus callitrichoides was a good phytoremediator for Cu. The
expected outcome of this research is to introduce cost- effective and eco-friendly technology to cater
environmental pollution. Hence, having the thorough study on the effectiveness of this technology might
contribute towards sustainable aquaculture practices in terms of ecological, economical, and social benefits.
